2: We can also use embedded questions as part of statements. The embedded question is a noun clause and can be used in a similar way to a noun. For example, we can use it as the subject or the object of the main clause.

Normal question: Where does she work?

Embedded question in a statement: I don't know where she works. (Here 'where she works' is the object.)

Normal question: Where does she work?

Embedded question in a statement: Where she works is very far. (Here 'where she works' is the subject.)

Forming embedded questions
We use the same rules with embedded questions in statements as we do with embedded questions in indirect questions.

If there is a question word, we keep it.

If there is no question word, we use 'if' or 'whether'.

We use normal sentence grammar (so we don't need 'do / does / did').

We use normal sentence word order (subject + verb, not the opposite).

We use a full stop and not a question mark at the end of the sentence.

Here are some examples of verbs that we often use with embedded questions:
